This must be one of the best kept secrets in Lapland. With a relatively large group of friends, we stayed at Hetan Kota for seven nights. The holiday camps has A-frames and log cabins scattered around in the forest and on the lake front, in an amazingly peaceful location. The manager, Jukka, and his wife are among the best hosts I have ever come across during me travels. They arrange programs, call around to get the best deals, cook super delicious dishes and go out of there way to ensure that the guests are happy. Coffee and tea were available throughout the day, and there is a small library with local books and brochures.
I stayed at one of the green log cabins further away from the A-frames. It had four double rooms on two floors, a living room, two bathrooms and two separate toilets, and of course its own sauna. The temperature outside dropped to -17 C but inside it was warm and cozy. We got towels but had to provide our soap, shampoo, toothpaste, etc.
There is also a larger sauna building on the lake shore, and Jukka cuts a hole in the ice for those who want to finish off the sauna experience with a dip in the frozen lake.
Public transport is not really available (there was one daily bus to Kittila during our stay,) so to be able to move around you will need your own car. The small town with shops and restaurants is about 5 km away. We went there only once (to buy beer) because the food provided in Hetan Kota was more then enough and we didn't need anything extra.
